The Assos TK 434 S5 Bib Knickers are the final amalgamation of 47 concept and prototype pieces that were carefully tested by Assos. These bib knickers have an impeccable fit and are ideal for warm spring, fall, or cooler summer rides. Type A.434 spandex fabric has more stitches per square inch to provide an increased amount of stretch and return, which means that the fabric will be more compressive but will never restrict movement. The fabric behind the knee applies less pressure, which allows your knee to bend freely without causing the fabric to shift. The front of the knee is sheathed in an insulated RXQ fabric panel to protect your joints from cooler weather. These cycling knickers feature the FI.Mille S5 chamois for unrivaled Assos comfort.
